Bogging full throttle
 

Just bought a used taotao pony 50 with 77 miles 2020. Ran it to 200 miles and did all the maintenance oil, gas filter, plug but now I have no power. Starts great engine runs great on the stand but when I get on it im having trouble going on the flat. Any suggestions? ngk iridum 7544 plug

Hi, it sounds like your ignition cable is loose. Maybe tiestrap it to your carb. But bogging can also be a used spark plug.
